Original application filed May 22, 1919, Serial No. 298,980; Divided andithis application filed December T 0 all whom it may concern:

Be it known that I, GEORGE S. I'IALL,ZL

citizen of the United States, residing at #298,980, and relates in particular to the mechanism for testing the radiator for leakage, and locating the leak.

The principal ob'ect of the invention is to provide a tank adapted to be filled with water and in which the radiator may be placed, and means for forcing air under pressure into the radiator when immersed in the water, so that the resultant bubbles of air will locate the leak.

Another object is to provide a means in the tank so that the radiator may be moved up and down therein, to definitely locate the leak, and may also be turned around to position said location within easy reach of the repair man.

Another object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly efi'ect1ve for the purposes for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claim.

In the drawings similar characters of reference indicate the corresponding parts in the several views.

Figure 1 is a side elevation of my improved table.

Fig. 2 is a top plan view thereof.

Fig. 3 is a longitudinal section taken relatively on a line 33 of Fig. 2.

Referring now more particularly to the characters of reference on the drawings, the numerals 1 and 2 denote a pair of table tops of any suitable dimensions and spaced apart for the positioning of a rectangular open Serial No. 344,505.

topped water tank 3 therebetween. Side members 4 connect the table tops and sustain the tank, the entire unit being supported onlegs 5 of a suitable height. Centrally positioned in the bottom of the tank 3 and extending a suitable distance therebelow is a cylinder or well 6 in which is adapted to slide ahollow guide or plunger 7, the same being held from turning in the well by means ofa vertical lug 8 running the full height of the well and fitting into a recess 9 inthe plunger 7'. The same result may also be obtained by making the well and plunger squa're.in cross section; A drain cock 3 is set in the bottom of the tank 3 to drain the same.

On the plunger is secured a vertical sleeve 10, in which is turnably mounted a post 11 which supports and has "secured thereto on itsupper end a platform 12 of any desired and suitable shape and construction.

A pulley 13 is mounted in the plunger 7 centrally thereof, the top of the plunger being provided with slots 14 therein for the passage of a cable 15 therethrough, which cable is secured to the top of the cylinder at one end, then passes through pulley 13 and then around pulleys 16 arranged to carry the cable above the line of the water in the tank 3, running thence to and being wound on a shaft 17secured to and extending outside the frame 4. The shaft 17 is turned by means of a hand wheel 18 thereon, and is adapted to be held in any desired position by some such means as a pawl and ratchet 19.

Low and high pressure air tanks 20 and 21 respectively are located under the table 2 and the tank 3, the high pressure tank being supplied by means of an air pump 22 driven by an electric motor 23. The low pressure tank is filled to a desired pressure from the high pressure tank by means of suitable piping therebetween controlled by a valve 24:. Behind the tank 3 is a dial and control board 25 having air gages 26 thereon for the air tanks, and gas and air controls 27 and 28 respectively for blow torches 29.

A valve 30 controls the air supply from the low pressure tank to the radiator being tested, a small hose being attached onto the end of the pipe 31 controlled by the valve 30.

One or more fire pots 32 are also included in the equipment, being connected with a gas,

supply.

A plurality of horizontal and slidable bars 33 are fitted in the table to one side of the tank, the described in the oopending application'for patent hereinbefore mentioned. and which has since matured into Patent No. 1,350,866, dated August 24th, 1920.

In the operation of the device, when a leaky radiator is to be repaired, itis first placed on the platform 12, the tank'3 being filledwith water and the platform positioned "so that the radiator is entirely submerged.

Air from the low pressure tank 20 is then admitted to the radiator and the tion of theleak will be evident from the resultant bubbles of air rising through the water. By then turning the hand wheel 18 to raise the platform 12, the radiator may be gradually raised from the Water till the bubbles cease, at whiohpoint in the thickness of the, radiator it is evident the leak' is located. By turning the radiator by hand, this being possible bymeans of the turnable post of the pedestal, the point of leakagemay be brought within easy reach of the mechanic. This leakfmay then be soldered while still retaining the radiator on the platform, or it may be taken off and the'tables 1 and 2.

Thus, from the foregoin placed on either one of urpose of thesebars being fully eneral locadescription it s will be readily seen that have produced such a device as substantially fulfils the object of the invention as set forth herein.

While this specification sets forth in'detail the present and preferred construction of the dev ce, still in practice such deviations from such detail may be resorted to'as do not form a departure from the spirit of the in I vention as defined by the appended claim. Having thus described my invention what VI claim as new and useful and desire to se cure by Letters Patent is An apparatus for testing leaky radiators" including in combination with a work bench provided with a tank containing air under pressure, an open-topped water'tank posi-r tioned on the bench, a platform in the tank for holding a radiator thereon, the radiator being connected with the air tank,a well in the bottom of the tank, a plunger slidabl'e in the same in the Well.
